A fet, EG the KSC5026 is a voltage operated device yes? No current flows into the gate, so how does 10uA base current translate between a BC546? This mosfet testing has me foxed on my CT, there's no xV per step and a mosfet is tested in SC mode. Transistors really make my brain hurt, there's so many parameters, a typical Q datasheet is a lot busier than a valves, big steep learning curve.

Thanks, think I tried that, will try again with a fresh 431, might have killed the one I was testing/mucking about with.
